Part A: divide the miles she biked in the amount of time she took. so, 21/4= 5.25. Her average speed is 5.25 miles per hour.
Part B: If she bikes at the same rate (21 miles in 4 hours), then she would take 8 hours to bike 42 miles because 21+21=42 and since she takes 4 hours to bike 21 miles, then it would take her another 4 hours to bike another 21 miles
A correlation is simply used to determine whether a relationship exists between the variables.
<h3>How to illustrate the information?</h3>
The information is incomplete and an overview will be given. The correlation shows the relationship between the variable.
This can be explained in a numerical form that's known as the correlation coefficient. This shows that strength of the relationship.

Answer:
0.27 lt/s
Step-by-step explanation:
80 liters in 5 minutes
5 minutes are 300 seconds (5x60)
We know how many seconds we need to fill up the tank (300 seconds for 80 liters). Now we need to know how many liters we can fill up in 1 second, as the question requires "liters per second".
80 lt / 300 sec
X lt / 1 sec
80 x 1
---------- = X
300
X = 0.2666666...
X = 0.27 lt / s
Step 1- Find the Greatest common factor (GCF)
GCF = 3
Step 2- Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(15x^xy^2/3 + -3x^3y/3 + 75x^4/3)
Step 3- Simplify each term in the parentheses
3(5x^xy^2 - x^3y + 25x^4)
